Description

In FreeBSD it is possible to host an vlan(4) with a different mac address from the parent.
This needs the parent interface in promiscuous mode, which at present days is not much of a issue.

Linked report here http://forum.pfsense.org/index.php/topic,34094.0.html.

Possibly an option should be given to people activate this issue.

Revert ticket #1337

FreeBSD is not happy with simple set VLAN to use a different MAC
address. Revert it for now and prevent users to change VLAN interface
MAC address.

With SG-5100 and XG-2758 on `2.4.4.a.20180824.1144` (which isn't the latest build, but should include whatever the fix was on `1337`) .. added a VLAN, assigned it as an interface with a static IP on both appliances, enabled the parent interface (no IP set, just enabled so the VLANs could use the interfaces) ... added a allow any rule on the VLAN interface on both pfSense. From either pfSense, I could ping the other. Then on one, I spoofed the VLAN interface mac as `DE:AD:BE:EF:CA:FE`, went to ping and now it fails. Remove the spoofed MAC, pings succeed again.

I his a valid test?
